Curcumin certified reference material was separated by silica gel column chromatography and recrystallization method. Its chemical structure was identified by UV,IR,MS and NMR. The homogeneity and stability were systematic checked. A cooperative certification was conducted with 8 qualified laboratories. The results showed that the certified value of the reference material of curcumin was 99.78% with the expanded uncertainty of 0.13% (k=2) in confidence coefficient of 95%. The reference material of curcumin can conform to the technical requirement of the certified reference material. The materials can be used for method validation and quality control of regarding products.
